DuetWifi Hardware Source Files on Github
-
For those of you who want to explore or modify the Duet Wifi hardware the full KiCAD source is now available on Github:
https://github.com/T3P3/Duet/tree/master/DuetWifiv1.0I will also be updating the documentation to reflect the hardware changes for the production boards
The source is released under the terms of the License agreement:
https://github.com/T3P3/Duet/blob/master/LICENSEEffectively this is the CERN Open Hardware License version 1.2 with a couple of additional terms to protect our Company Logos and the Duet3d logo.
Adrian Bowyer and I chose the CERN OHL when developing the Duet 0.6. As a derivative work, the DuetWifi is also distributed under this license. At the time we believed it was the best open hardware license available and I still believe this is true today.

Thanks for posting this. It might come in handy down the road.
I had a look through the schematics and noticed that Fan1 doesn't have the 10k pull-down between the gate and ground like the others have. It probably doesn't matter if the processor has internal pull downs.
-
The processor has an internal pull up enabled by default. Fan1 is typically used as a thermostatic hot end fan, so we wanted it to be on by default, in case a user resets the board while the hot end is still hot.

Makes perfect sense. I just noticed that "one of these things is not like the other".
